Abstract
Relative reproductive success of male bicolor damselfish, Eupomacentrus partitus, was measured as the number of egg batches obtained per week per male during a 14-month field study. Large and consistent differences in spawning success, observed in seven colonies containing 23 males, demonstrated that mating was non-random. Various physical and behavioural characteristics of males were also monitored. Significant correlations (P<0.05) were found between reproductive success and four variables: frequency of courtship, inter- and intraspecific aggression, and total length. The importance of other factors such as size and location of male territories and time allotment to various activities was also considered. The interactions between these variables, as well as preliminary observations of spawning, suggest that intersexual selection, that is female choice of mates, is the dominant process in sexual selection in this species.
